PNG leader on six-day Australian visit

Papua New Guinean Prime Minister James Marape will arrive in Australia on Sunday for a six-day visit.

It coincides with a fortnight of parliamentary sittings in Canberra and will be the first guest-of-government leader visit since the re-election of the Morrison government.

"The bond between Australia and Papua New Guinea is unique and enduring, based on the personal, professional and historical ties between our peoples," Prime Minister Scott Morrison said.

"The people of Papua New Guinea are part of our Pacific family - our wantok, our vuvale, our whanau."

Talks are expected to focus on trade, investment, labour mobility, defence and security.

"Australia is committed to stepping up our engagement with Papua New Guinea and the Pacific more broadly in support of a region that prospers while being safe and peaceful, with each sovereign country in charge of their own futures," Mr Morrison said.

Mr Marape will be accompanied by his wife Rachael and several ministers.
